Part Number: LM2917-N The test results indicate a measurable internal variation in LM2917 devices manufactured after 06/29/2023 (Lot: 3099313EM3, Philippines) compared to earlier lots. Both VI curve tracing and functional circuit testing confirm that…
Part Number: LM2917-N Other Parts Discussed in Thread: LM2907-N , Tool/software: Which part number for the 14 pin variant doesn't have the zener? I can't seem to dig that out the spec sheet.
Part Number: LM2917-N Hi
The many permutations and design options for the LM2917 leave me unsure we have the design right. I wanted feedback if the circuit is correct. Requirement: fan tachometer output - need to trigger indicator (1/0) whether fan…
Hi Ali,
Ali Khan said: This typical application getting signal from secondary winding of ignition coil(correct me if i am wrong). I believe that's why there is a voltage divider to reduce input voltage for TACH+ pin. While I have already converted 12Sq…
Part Number: LM2917-N Hi
Upon re-examination, we started to wonder. - if the comparator is "zero crossing", and the input signal goes from 12V high to a low of a few tens of millivolts (or ven exactly 0) - how would the comparator trigger in the circuit…

Part Number: LM2917-N Tool/software: Dear Sir/Madam,
1) Whether can we make use of LM2917MX-8/NOPB for the application of PWM signal (where Duty cycle will be varying) to voltage conversion?
2) If this PN is not suitable then could you please share…
Part Number: LM2917-N Tool/software:
I am trying to push 1Khz-10Khz 0-5v Square-wave from my PLC and output between .8v -4v DC. I have the signal coming in I just do not seem to be getting voltage out. I KNOW I am doing something wrong. Any thoughts…
Part Number: LM2917-N Hi,
I intend to use LM2917 to read RPM of motorbike on an MCU by reading analog voltage by following circuit.
I want to remove the meter from this reference diagram and read the RPM on any MCU by reading analog voltage. From…
Part Number: LM2917-N Hi,
Just to be double sure some guidance is needed to validate the circuit as much help is not available. This tachometer and speedometer would be for motorbikes only. For speedometer hall effect sensor is used and for tachometer…
